SKU CH-VGE9-VD4WN

200 mm hydraulic-bearing case fan with red LED running at 400 RPM and a 4-pin power connector

  • Large 200 mm frame moves more air at low speed

  • 400 RPM keeps noise low while still circulating air
  • Standard 147 mm hole spacing fits most 200 mm mounts
  • 4-pin power connector plugs directly into PSU

200 mm case fan with hydraulic bearing

The SXDOOL 20030 is a 200 mm square case fan designed for desktop chassis cooling. It suits builders who want a single large-diameter intake or exhaust. The 400 RPM top speed keeps acoustic output low while still moving air across a broad surface. It is not intended for users who need high static pressure for dense radiators or restrictive filters.

Low speed headroom and mounting pattern

At 400 RPM the fan delivers gentle airflow suited to positive-pressure builds or quiet workstations. The hydraulic bearing helps maintain consistent rotation at this low speed range. Mounting holes sit 147 mm apart on each side with a 208 mm diagonal spacing, matching common 200 mm frame standards. The 30 mm thickness fits most standard fan bays without clearance issues.

Direct 4-pin power supply connection

The fan draws power through a standard 4-pin peripheral connector from the power supply unit. This bypasses motherboard headers, so speed is fixed at the rated 400 RPM with no PWM or voltage control. Builders who want variable fan curves or software monitoring will need a different interface. The red LED illuminates whenever the connector receives power.

Soalan tentang produk ini

Will the 200mm frame and 147mm screw spacing line up with my older full-tower case?

The fan measures 200mm by 200mm by 30mm with mounting holes spaced 147mm apart, matching the common 200mm standard used on many full-tower chassis.

How can I confirm the hydraulic bearing is running at the rated 400RPM after installation?

Connect the 4P power supply interface, then check the fan speed in BIOS or a hardware monitoring utility; it should report approximately 400RPM.

Does the box include mounting screws or only the fan with its 4P power supply connector?

The package contains the 20030 fan with a fixed 4P connector; mounting screws are not included and must be sourced separately.
